The essence of the solution is a unit-construction system of a rotary gripping device facilitating an optional, quick and the exact angular slight tuning of the clamped part in view of the selected initial point with the option of random complementary angular corrections as far as the size and sense are concerned. The main parts of the device are represented by positioning a section, containing in its central hole accessories for putting in and clamping the parts. The positioning section is interconnected through a positioning arbour with an arresting ring, the rotary movement of which is coupled with a special worm gear drive enabling simultaneous evaluation of the angle values. It may serve as a very accurate rotating clamp at most various machining operations, angular quality meters of machined parts, possibly equipment facilitating combination of production and control operations, i.e. right on the machine-tool table.<IMAGE>
